Chapter 10 Haloalkanes and Haloarenes 

Halogens and halogens are an important chapter in 12th-grade chemistry. The questions for this chapter presented in the NCERT chemistry textbook build students' conceptual knowledge and confidence. Vidyakul’s experts designed NCERT notes for Chapter 10 of Grade 12 Chemistry after selecting their questions and answers in this chapter.

Points to Remember

Below we have provided some of the important points to remember for NCERT Class 12 Chemistry to ace your exam:

• In water, haloalkanes are only very slightly soluble. They do, however, dissolve in organic solvents.

• Aryl halides are much less reactive than haloalkanes in nucleophilic substitution reactions.

• In the electrophilic substitution reaction of haloarenes, halogen is deactivating but o, p-directing.

• The Elimination reaction occurs when two groups or atoms are attached to two adjacent carbon atoms, and multiple bonds form simultaneously between these carbon atoms.

• When alkyl chlorides react with AgNO3, a white precipitate is formed that is soluble in alcoholic ammonium hydroxide.

• When alkyl bromides react with AgNO3, they form a yellow precipitate that is only slightly soluble in alcoholic ammonium hydroxide.

• When alkyl iodides react with AgNO3, a dirty yellow precipitate is formed that is insoluble in alcoholic ammonium hydroxide.

• When plane polarised light passes through the solutions of certain compounds, it rotates. Such compounds are known as Optically Active compounds, and the phenomenon is known as Optical Activity.

Topics and Sub-Topics

At Vidyakul, we offer premium notes for Haloalkanes and Haloarenes Grade 12 Chapter 10. It teaches the common name of Alkyl Halide. Vidyakul notes help identify a number of haloalkanes and halogens according to the IUPAC nomenclature system. After learning these concepts, students can easily describe halogen and halogen preparation reactions.
